All your previous reviews with ratting are safe and will remain the same after you install the ReviewX plugin. But we assume that you’re not expecting the multi-criteria based ratting for those previous reviews as by that time you weren’t using ReviewX 😉
If you uninstalled the ReviewX plugin then you’re not going to lose any of the WooCommerce product reviews data. And the same way, we assume that you’re not expecting the multi-criteria based ratting once you uninstalled the ReviewX plugin.
